Summarize each of the inventions you studied this week and how they impacted history.
Next, answer one of the following:
a) If you wanted to become an engineer who makes integrated circuits, what steps do you need to take? Use the Internet to perform research and find out.
b) What are some uses of laser technology that you would like to see invented that don’t yet exist (that you know about)?
Bonus Question (This is hard, which is why it’s optional. It’s just for fun.) – Assume you had a twin brother or sister, and you were both born at the exact same time and second (not really possible, but just assume for the sake of this question). Assume you both go camping together in the woods. One of you sleeps at the bottom of a tall observation tower, and the other sleeps up top, in the tower. According to Einstein’s theory of general relativity, one of you will be older than the other in the morning. Which one of you will it be, and why? Use the Internet.
\Polio is a dangerous disease that kills people. Aside from war, polio was one of the biggest fears in American history. Polio can paralyze one of your limbs. Franklin Delano Roosevelt died of polio. It was a sad life for those who caught polio. Jonas Salk invented the polio vaccine. He wanted to study under something other than the medical field, but his mom wanted him to be a doctor. Salk felt he would help more people by being a medical researcher, so he became that. In 1955, the polio vaccine was a thing. There are two ways to use the vaccine: swallow it, or inject it. It’s more dangerous to swallow it, since the bacteria is still alive, just weakened but is cheaper. It’s much safer to inject the the bacteria because it’s dead although it’s more expensive. People were not scared anymore. Polio didn’t threat people. This was my favorite invention.
An intermodal container is a giant metal container that has cargo in it, and they stack on top of each other. They fit like puzzle pieces. They can also be called cargo containers. Malcolm McLean invented the cargo container. He realized that unloading cargo was hard and tiring, and things got stolen easily. It became much cheaper to ship things. You can install air conditioning or heat in the cargo containers.
An integrated circuit have transistors and help with computer logic. Two men invented the integrated circuit. Their names were Noyce and Kilby. Integrated circuits are expensive to manufacture, but it’s worth it. It has a lot of steps to manufacture. Because of the integrated circuit, the military weapons got better and you could control them easier. The Apollo rocket ship had many integrated circuits. Without these, technology would not be a thing.
Laser stands for Light Amplification by Stimulated Emission of Radiation. A laser uses energy and atoms to produce strong light. Charles Townes invented the laser. He named after a similar light device called the “maser”. Lasers have many benefits. Some can be used for surgery to cleanly cut things. Weak lasers can be used in carpentry to check if the wood is even (my dad does this a lot since we’re trying to make our “unfinished” basement “finished”). They can be used with CDs and DVDs too. Lasers are very beneficial, and without them, we would not have these stuff.
Imagine two people; their names are 1 and 2. They’re both in space, and in high tech spaceships. 2 goes back to Earth. 1 decides to zoom away into space at light speed. 1 travels for what seems to be a year to them, and go back to Earth. 1 only aged a year, but 2 has aged many years. Why? For 1, time slowed down since they were going incredibly fast. They barely aged. But for 2, 1 was going so fast and stayed away many years. This theory involves light physics, time, and speedEinstein’s theory of general relativity
Assume you had a twin brother or sister, and you were both born at the exact same time and second. Assume you both go camping together in the woods. One of you sleeps at the bottom of a tall observation tower, and the other sleeps up top, in the tower. According to Einstein’s theory of general relativity, one of you will be older than the other in the morning. Which one of you will it be, and why?The week’s question I am choosing to answer
For the twins, the twin who slept under the tower (1) is older. The earth is spinning slower than the top of the tower, and therefore, the twin who slept on the top is younger.
